The remains were discovered in the nearby village of Aroos. With five individual specimens, the total weight of the meteorite is estimated at {{convert|150.29|kg|lk=on}}.[https://docs.google.com/viewer?a=v&q=cache:X1Ox7OHi3b0J:www.lpi.usra.edu/meteor/docs/mb16.pdf+meteorite+azerbaijan+1959&hl=en&sig=AHIEtbSZyh_Z7JdN29hCLFzvn88yuOaCMA Permanent Commission of Meteorites of the International Geological Congress] The meteorite is kept in the Institute of Geology of Azerbaijan National Academy of Sciences.

The eyewitnesses saw the bright bolide flying through clouds from southwest to northeast. The falling was accompanied by a bright, blinding flare brighter than solar illumination and a noise similar to rolling thunder. The illumination embraced the area of ca. {{convert|2800|km2|mi2}}.Soviet Azerbaijan Encyclopedia (Baku, 1981), vol. 5, p. 80 The fall of individual pieces was accompanied by a whistling and drone, resembling that produced by a jet aircraft or missile. The examination of chemical and physical properties of the meteorite was led by Azeri researcher Mirali Qashqai.

At the request of American scientists, the Soviet Meteorite Committee sent the meteorite samples to California University, Cambridge Astrophysical Observatory and the Institute for Nuclear Researches of Chicago University, as well as to CERN. One of the samples was preserved in Fersman Mineralogical Museum.
